Abstract

A weapon control system is disclosed which includes system electronics providing control and drive electronics for the weapon control system, a weapon mount for supporting and firing a weapon in accordance with commands from the system electronics, a remote control including a visual display and hand controls for operational control of the weapon control system from a position distant from said weapon mount, and a system disconnect for removal of control of the weapon from the weapon control system and for safety interlock to prevent accidental firing of the weapon. The weapon mount is adapted to support and fire a variety of weapons. A gyro stabilization assembly is mounted on the weapon mount and operatively connected to the remote control and the system electronics for allowing line-of-sight weapon and integral sight stabilization.
